about the 1989 Chevrolet Sprint

Question type: Maintenance & Repair

My 89 chevy sprint 1.0L 3 cyl. Non turbo has issues starting. I am not a mechanic and have been researching alot on google to slowly investigate my issue. I've had an ongoing problem for three weeks now and it is definitely my timing. I went a bought new spark plugs,new spark plug wires a new timing belt and new serpentine belt.I went ahead and have tried setting my timing and for a total of about 30 hrs I have had no success. Today I found a link to do with a worn crank pulley keyway, my center bolt does goes hand loose meaning I can take it off by hand without wrenches and I was able to pull the pulley off with my hands....both seem like red flags.....I did notice a bad wobble prior to these issues happening. So now I need a walk trough on how to replace the worn crank pulley and learn how to spot yhe the obvious signs of damage both on the pulley, keyway amd crankshaft itself. Question. First step.....after taking pulley off.....do I take the bottom cover of the engine off to access the crankshaft? Is this a no no or what.....any information is greatly needed and appreciated.

Never hard of a crankshaft pulley being loose! Why was it loose? Did
someone mess with it and not tighten properly? Take it off and
inspect the pulley, keyway, key and shaft. Sounds like it wobbled
and thus wore the tight fit that is normally there?
